PHP - function which initializes variables

Question

I would like to make cross variables in my template via the router.

I want to do:

$router->with(array(...));

Here is my with function:

public function with($vars)
{
    if(is_array($vars))
    {
        foreach ($vars as $key => $value)
        {
           $$key = $value;
        }
    }else
    {
        die("La fonction with() demande un tableau en paramètre.");
    }
}

Am I on the right track?

I wouldn't create all those variables. Just use the array and access the data with the key. — Rizier123

utterly useless, since those variables would exist ONLY within your with() function, and be destroyed as soon as the function exits. — Marc B

yeah, I forgot the extract() function. Everything is revised and functional, thank you — Jason Van Malder

You can instead just extract your keys as vars in your template. Like this

function with($view, array $data = []) {
    extract($data);
    require $view . '.php';
}

with('some_view', [
    'name' => 'John Doe'
]);

Then you can use it in your view, like so

<h1><?= $name ?></h1>
